Installation and Setup

Turning on the Analyzer for the First Time

Turning on the Analyzer for the First Time

Plug in the power cord.

WARNING If this product is to be energized via an external auto transformer for voltage reduction, make sure that its common terminal is connected to a neutral (earthed pole) of the power supply.

CAUTION The analyzer is shipped with a a transportation disk inserted in the disk drive to prevent damage to the disk drive during transportation. This transportation disk, or a blank floppy disk, should be inserted in the disk drive whenever transporting the analyzer.

Do not leave a disk in the front-panel disk drive while turning the analyzer on. Also, ensure that the transportation disk is removed from the drive.

NOTE

Do not connect anything else to the analyzer yet.

Press the power switch (located in the lower left-hand corner of the analyzer’s front panel) to turn the analyzer on. See “Front Panel Overview” on page 22.

NOTE

The instrument requires >2 minutes to power-on.

Information Screen

An information screen appears during the initialization process. The information screen contains the analyzer product number and a URL for accessing product support information on the World Wide Web. See “Additional Information” on page 2.

NOTE

The information screen displays for approximately 10 seconds before the

 

initialization process is complete.

 

Record the firmware revision and serial number, and keep it for reference. If

 

you should ever need to call Agilent Technologies for service or with any

 

questions regarding your analyzer, it will be helpful to have this information

 

readily available. You can also obtain the firmware revision and serial

 

number by pressing System, More, Show System.
